Ahem. We've found that the real issue lies with the fact that that
the required graph is a *two-cycle* log on the x axis. This appears
to involve a change of scale (i.e. log formula) halfway along the x
axis, effectively the same as abutting two distinct charts, but with
rigid controls on the physical dimensions and ranges of scale
values used for each demi-chart.
More checks are in order (because I really don't yet understand the
implications of "one cycle" vs. "two cycle" in the log chart world),
but that appears to be the gist of the real problem, and not
something that TeeChart can do directly for us. In contrast, doing a
simple log(x), linear(y) chart in TeeChart is as easy as the
proverbial.
